Which platform delivers clearer pricing differences across storage and compute?

The platform that delivers clearer pricing differences across storage and compute varies by workload shape; in snowflake vs bigquery evaluations, Snowflake centers on per-warehouse compute and compressed storage, while BigQuery centers on per-query on-demand and flat-rate slots.

1. Per-warehouse scaling and auto-suspend

• Virtual warehouses align compute to team or pipeline boundaries with independent scaling.
• Metering occurs while warehouses run, enabling pause-based savings between jobs.
• Budget visibility benefits from dedicated clusters mapped to cost centers or projects.
• Isolation reduces noisy-neighbor risk, keeping latency steady during parallel tasks.
• Autosuspend policies curb idle burn by pausing capacity after inactivity thresholds.
• Auto-resume policies restart capacity just-in-time, balancing speed and spend.

2. On-demand per-query billing and slots

• Per-query mode bills bytes processed, while slots offer time-based capacity reservations.
• Serverless execution removes cluster sizing, focusing on query design and data layout.
• Clear unit economics emerge from bytes scanned and slot utilization targets.
• Spend caps, reservations, and workload management protect budgets at scale.
• Slot commitments stabilize spend for steady demand and predictable throughput.
• Flex slots and autoscaling pools address bursts without manual provisioning.

3. Storage pricing and compression

• Columnar storage with compression reduces footprint and long-term retention costs.
• Separation of storage and compute simplifies independent scaling decisions.
• Lower footprint trims recurring charges and accelerates scan-heavy queries.
• Lifecycle policies and archival tiers optimize cold vs hot data placement.
• Time-travel, cloning, and snapshots enable safe experimentation with minimal copy.
• Storage metrics guide partitioning, clustering, and retention horizon choices.

4. Egress, cross-region, and cross-cloud fees

• Data movement across regions or clouds introduces additional network charges.
• External tools and BI connectivity can increase outbound traffic volume.
• Architecture choices that minimize movement preserve margin on shared datasets.
• Regional affinity for compute and storage reduces recurring transfer overhead.
• Private service endpoints and peering lower path costs and tighten security.
• Budget alerts on egress guard against silent cost creep during scaling.
